Fairly certain that that statement is false, the comparator is intended to detect a block that is not in the detecting location, and this doesn't explain the continual repetition or the fact the repeaters next to the flickering one can begin flickering themselves. (The command block next to the comparator is detecting a different block in the distance, running a /testfor (~1 ~1 ~ above button locations) 124, and is in no way looking for the repeaters.)
The front command block was for a "/setblock replace" command in another part of my world, the back command block uses the "/setblock replace" for the repeater.
